How to Fix iOS 26 “Unable to Check for Update” Error
1. Check Wi-Fi and Network
- Switch to a strong Wi-Fi network; avoid mobile hotspots.
- Restart your router and modem.
- Turn off VPN or Proxy if you’re using one.
2. Restart Your iPhone
- A simple restart often clears temporary glitches.
- Press and hold Power + Volume Down, slide to power off, wait a few seconds, then turn it back on.
3. Check Apple’s System Status
- Go to Apple’s System Status page.
- If the iOS update server shows “issue” or “maintenance,” just wait — it’s on Apple’s side.
4. Fix Date & Time Settings
- Go to Settings > General > Date & Time.
